Just fyi, the tracking is only for ads and all tracking is gone once you remove the ads through Ultra or the one time payment. I don't expect this to please most, but as someone who has used Sync for Reddit for basically my entire existence on Reddit, I've only paid a couple bucks back then for an app I used every day. So far I feel right at home here and I'm willing to pay after some time and seeing how this goes. The number of options is only growing and Sync is bringing new users to Lemmy either way. I've been through like 6 other Lemmy clients and Sync is still the one for me.
Edit: Several users confirmed tracking wasn't present after removing ads.
By not pinning apps to every dock position in the Pixel Launcher, it suggests apps based on your usage. It shows a combination of recently opened apps, ones you often use alongside an app you've just opened, and ones you usually use at certain times of day. I left the 3 slots open some time ago to see how it works and just left it like that. I kinda like it.
